L'Be it known '..that I', Jorrit.' a "fj-1 `citizen fof. r the.4 United .j States, ',:residi'ngf at kro'n, in thevcounty of Summit and State i of Ghio, have invented certainnew and useful Imorovements in Bench-.Vises, of which the fo owingis a specification.

' This invention pertains to a double swivel bench vise constructed and 'adapted to. operate substantially as shown and described and particularly pointed out Vin the claims.

In the accompanying drawings, Figure 1 is a side elevation. of thev complete vise and Fig. 2 is a longitudinal sectional elevation thereof. Fig. Slis an elevation ofthe front orjaw end. Fig. 4 isV a cross sect-ion on line 4 4, Fig: 1. Fig. 5 isa sideA elevation of the `friction collar or belt, and Fig.. 6: is

'an edge view thereof. Fig. Z is. a detailv of the yoke.-

The invention herein is. an improvemen on the construction disclosed in my application executed April 23, 1915 and bearing Serial Number 32,101, filed June 7, 19.115., and the invention possesses certain differences in construction and advantages. in operation over said application as. will bel seen in the further description herein and is clearly shown in the drawings. Thus, in the present case the so-called fixedy jaw J andthe movable jaw J are operatively related, as' before, the jaw J having a tubular body, or extension 11 projected into the bore of the body 6 of the fixed jaw and slidable lengthwise therein within the limits of the key-way or groove 3 and a preferably flat side plug 7 engaged in said way through the wall of the outer jaw, as before, to limit the withdrawal of the said movable jaw.

In the former construction I employed two supporting members or yokes for the fixed jaw, but in the present case I have a unitary or single yoke or yoke member Y but of two diameters corresponding to the two diameters of the body 6 of the fixed jaw and serving as a support and bearing for the said fixed jaw, in a measure after the manner of two separate yoke members in said application but still differing therefrom in this particularly,-that the present yoke, Fig. 7, is not only unitary but has a single annular or solid hub 4, which is adapted to be seated in the base B which is split at its front and adapted to be clamped tight upon said hub by means of a screw or bolt. The said yoke also has a recess 5 tranSVelSGly in y Y Sreeilfwiftoil ofgflftt'erslaent- Patented 18, 1916. Application.mentale 7,111,915. 'l' 'sri-ai No. aagvso i i recei-ve 'theasplit friction-clamping collar C,

- and which serves las a gripping or clamping medium for the tubular differential body 6 ofthe xed jaw, as shown. The said collar fills the said recess 5 and extends entirely around the body of the outer jaw and. is split transversely at its. bottom and has threaded bosses 8 at its sides through which the clamping screw 9 passes from side to side through said split, whereby the said xed jaw can be clamped` with great force and security as wellv as be conveniently released for rotation ofthe jaws when desired. It followsv that the yoke Y is. rotatable/in base Bexcept as it is secured by clamp. b andv that the two jaws are rotatable together. in the yoke'Y except asthey are clamped by collar C, the whole affordingacompound swivel wholly independent of each other. clamps may be tightened or released at the same time, orone may be tight and the other loose without releasing the jaws.y as they may be locked on stock therein. The screw S serves the usual purpose of operating the movable jaw, and the sleeve nut n in which said screw works has a collar 10 bearing against the inside of the otherwise closed end 12 of the outer jaw body while the said nut n pro-jects through said end 12 to the outside thereof and carries a friction clamping collar or cap 14 sleeved thereon and a nut 13 outside said cap to tighten the same against said end 12 and to bear rotatably against the surrounding edge of the yoke. This enables the two jaws to be locked in working relation on any stock engaged therein and to be axially rotated when gripped upon said stock regardless of the two swivels in the base and i'n collar C respectively. Of course the stock 1s clamped in the jaws by the screw S and this is not aected by releasing either of the two other swivels.

In the description and claims the word jaw or jaws is understood to include the tubular bodies thereof which are necessary portions of the said jaws or jaw mem' Both v outer jaw extension, the'purpose of this construction being to prevent the escape of the fixed jaw from within theI yoke but to permit free rotation thereof, subject to locking through the collar C. The straight bottom edge of collar C prevents the collar from -rotating when clamped on the jaws and holds the jaws firmly in respect to theyoke and base.

What I claim is: Y 1. In a vise as described, a jar-w supporting yoke provided with a hub on its bottom and a recess across its middle above said hub, jaws projectlng through said recess and a collar in said recess adapted to clamp upon said jaws.

` 2. A vise as described having a pair of jaws, a yoke for said jaws having a transverse recess open from above a split friction collar embracing said jaws in said recess and having bosses at each side and a screw through said bosses beneath said jaws and adapted to clamp the collar thereon.

3. A vise having a double swivel as described and comprising a split base, a yoke having a hub rotatably seated in said base and adapted to be clamped therein, a pair of jaws provided with tubular bodies vone within the other and extending through said hub, a split collar seated in said yoke and embracing said outer jaw body, and means to clamp'said collar on said body.

4. A vise having a yoke and two jaws supported therein and having tubular bodies one within the other, an operating screw land a sleeve nut engaged thereby extending through the end of the outer of said bodies and provided with a collar bearing aga-inst the inside of the end thereof, a cap over said nutvoutside said yoke and bearing against the same and the end of said outer body and a nut to clamp said cap frictionally against said end. l

' 5. In a vise as described, a pair of jaws, a

ibase and a` vyoke therein having a recess jaws and lock the same against rotation.

7 In a vise as described, a pair of jaws having tubular bodies one within the other,

a supporting base and a yoke therein sup-p porting said jaws having a transver'serecess with a straight bottom transversely beneath Y said jaws and a split collar about said jaws fitted to the sides and bottom of said recess and provided with clamping means at its` bottom adapted to hold the said bodies against rotation.

In testimony whereof- Iaiiix my signature yin presence of two witnesses.
